Science
Mechanism of Action
This advanced peptide exerts its effects through a sophisticated dual mechanism encompassing neuromodulation and anti-inflammatory pathways. It specifically inhibits the release of Substance P from cutaneous nerve endings, effectively reducing amplified sensory responses like stinging, redness, and swelling. Concurrently, DIPEPTIDE-1 promotes the release of met-enkephalin and enhances β-endorphin production, engaging natural opioid receptors to induce a profound calming and analgesic effect, thereby increasing skin's tolerance to irritants. Furthermore, it significantly suppresses the expression of pro-inflammatory cytokines (IL-1, IL-6, TNF-α), aiding in the resolution of inflammation and fortifying the epidermal barrier. DIPEPTIDE-1 actively stimulates fibroblast activity to promote the synthesis of elastin and tropoelastin, leading to discernible improvements in skin tone, elasticity, and a reduction in cutaneous sagging. Its action also extends to upregulating genes critical for barrier integrity, including Aquaporin 3, Filaggrin, caspase 14, and keratin 10, while potentially modulating muscle relaxation signals to mitigate expression lines.

Key findings
- 01 Demonstrated inhibition of pro-inflammatory factors (PGE2, NF-κB), leading to reduced redness, itching, and overall skin irritation. A significant reduction in burning and redness was specifically observed in response to capsaicin-induced irritation.
- 02 Effectively reduces exaggerated skin responses such as redness, stinging, and swelling caused by external stressors, concurrently enhancing skin tone and elasticity in anti-aging applications.
- 03 In a study involving 26 female volunteers aged 54 to 75 with sagging skin, this concentration visibly combated cutaneous sagging, improved skin firmness, and reduced the effects of gravity within one month.
- 04 Showed a substantial increase of up to 90% in elastin fiber synthesis compared to control samples. Separately, it increased the quantity of elastin and tropoelastin deposited in the extracellular matrix by over 94% following release from fibroblasts.

Dusting Analysis
Clinical research provides specific effective concentration ranges for DIPEPTIDE-1, from as low as 0.01% for anti-inflammatory benefits to 4% for significant firming effects. This precise data for targeted outcomes suggests that the ingredient is incorporated for its functional efficacy rather than at sub-efficacious levels for marketing purposes.
The Formula
Formulation
Stability
To maintain its active integrity, DIPEPTIDE-1 must be incorporated into formulations during the final processing phase, ensuring the temperature is maintained below 40 °C. Its efficacy is notably diminished in highly acidic or alkaline environments, necessitating strict pH control within its optimal range.
